Connecting VLAN Groups

The switch supports intra-VLAN communication using wire-speed

switching. However, if you have devices

in separate VLANs that must

communicate, and it is not practical to include these devices in a

common VLAN, then the VLANs can be connected via a Layer 3

switch (such as the SMC6724L3) or a router.

Multicast Filtering

Multicasting sends data to a group of nodes instead of a single

destination. The simplest way to implement multicasting is to

broadcast data to all nodes on the network. However, such an

approach wastes a lot of bandwidth if the target group is small

compared to overall the broadcast domain.

Since applications such as video conferencing and data sharing are

more widely used today, efficient multicasting has become vital. A

common approach is to use a group registration protocol that lets
